What's Changed

Full Changelog: https://github.com/questdb/questdb/compare/8.0.0...8.0.1

8.0.0

This one's a big one!

In brief, to get you to the goods quicker:

  • New VARCHAR data type over STRING default for ++compression & ++performance
  • 50% improvement over already fast SQL query performance
  • Data compression via system-level ZFS, previously Enterprise-only

And more...

Upgrade as soon as you can. Or start fresh and build out your use case.

If you're still reading, onwards for more detail, breaking changes, plus the PR breakdown.

New features 🐣

  • VARCHAR: Introduces the VARCHAR data type and a new type driver API. VARCHAR offers UTF8 encoded strings of variable length as opposed to the UTF16 and fixed length encoding found in STRING, for better compression and significantly improved performance.
    • Maximum size of a single VARCHAR field size is 268 MB.
    • A size of a VARCHAR column in a single partition is limited by 218 TB or disk size, whichever is smaller.
    • STRING is now considered a legacy type.
  • Data compression: Data compression for OSS! Full support for the ZFS file system and system-level data compression.
  • ALTER COLUMN type: Use ALTER TABLE SQL to convert column types.
    • Migrate between STRING, SYMBOL, and VARCHAR data types.

Breaking changes 💥

  • GLIBC upgrade: Upgraded GLIBC to a minimum of 2.28-amd64 and 2.33-aarch64.
  • ILP and TextImport changes: ILP and TextImport now create VARCHAR instead of STRING columns.
  • Jemalloc allocator: The default allocator is now jemalloc. Later updates include disabling jemalloc as the default allocator and removing jemalloc from no-jre builds.

Performance 🚀
